Specification of Letters Patent.

Patented April 17, 1906.

Application filed March 10, 1905. Serial No. 249,445.

To all whom, it may concern.-

Be it known that I, HUGO GERIKE, a citi- Zen of the German Empire, and aresident of Klein Schonebeck, near Berlin, Germany, have invented newand useful Improvements in Bung and Seal Closures for Casks, of whichthe following is a description.

The present invention relates to bung and seal closures for casks; andit consists of the details of construction hereinafter set forth, andparticularly pointed out in the claim.

In order to render the present specification easily intelligible,reference is had to the accompanying drawings, in which similar lettersof reference denote similar parts throughout both the views.

Figure 1 is a vertical section through the bung-closure, with theprotecting-cap for the seal; and Fig. 2 is a plan of Fig. 1.

Referring first to Figs. 1 and 2, the bunghole of the cask a is recessedfrom the outside of the cask to form the annular shoulder f, and on thisshoulder is properly fixed, by means of a screw 1), aninternally-threaded metal ring I). The bung c is of wood and is reducedat the inner side to form the upper annular flange c, beneath which onthe reduced part of the bung, which said reduced part fits snugly intothe interior part of the bung-hole, an externally threaded metal ring (1is securely mounted and held against rotation by a screw d. Beneath thisring a washer g, of resilient packing material, such as india-rubber, isprovided. The top of the bung is provided with recesses c for thereception of a key 6 (shown in dotted lines in Fig. 2) and by means ofwhich the bung is screwed into the ring I). Then the said bung has beenproperly screwed into the ring I), the packing-ring g will serve totighten up the closure, and only wood surfaces will be presented to theliquid within the cask or at most a very small surface of thepackingring, while the outer side of the bung lies flush with the outersurface of the cask, so that the seal 8, Fig. 2, will be applied to woodonly, and will thus remain better in position, as it is very difficultto apply a seal to the cask when the bung is of metal. l/Vhen the sealhas been applied, the protecting plate or cap 7 is placed over the same,its downwardlybent ends being sprung into the inclined slots 8 of thecask, as will be readily understood.

With the above invention the great advantages are attained that the topof the bung'is flush with the outer surface of the cask, while theliquid in the cask will always be in contact with the wood of the bungor with the washer, but will not come into contact with the metal partsof the closure.

I claim as my invention In a cask-closure, the combination of acaskstave having a bung orifice with inwardly-projecting annularshoulder f, an internally-screw-threaded metal ring to fit the bung-holeabove the said shoulder f, and having its upper surface lying below thesurface of the cask, a bung or plug having a reduced portion to extendthrough the stave of the cask and fit into the opening formed by theannular shoulder f, an externally-threaded metal ring fitting on thesaid reduced part and adapted to screw-thread into the metal ring of thebunghole, a packing-ring located beneath the lower edge of the saidmetal ring of the plug and above the annular shoulder f and a flange onthe said bung or plug to fill out the enlarged part of the saidcask-hole and having its upper surface flush with the outer surfaceofthe cask substantially as described.

In testimony whereof I afiiX my signature in the presence of twowitnesses.

HUGO GERIKE.
